Optical fiber confocal image forming apparatus having a control means confocal near variable

摘要

(57) Abstract The confocal image formation device which uses the optical fiber is offered, the said device adjoining to the light condensing edge (70), of confocal optical transmission means has the light condensing edge (71), the part where the near-confocal light which is emitted from the place where it is larger than the distance whether only the near-confocal light (S '', T '') which is emitted from the dot of target ones (S and T) which are located to the upper part of the focal plane and within distance of the range which has the lower part, the gap which inside the aforementioned range would like to be chosen of is chosen from the remaining part in general, transmits with the kind of manner which is separation possibleTry to do. In addition as for this device, aforementioned it has possessed the variable selection means (73,76) expulsion the part which is chosen from detection.
